Hello
My MCU Firmware FOTA test is currently completed with UDP, but there is a problem with the transfer speed.
It takes 30 minutes to transfer 200kbyte binaries…
I’m sending the UDP data in 512 bytes.
I wonder if it’s normal to take 30 minutes…
Mangsangtae is very good.
200k/512=400 timers
30*60s/400=4.5s
Depending on the time you spend and the size of the packet, a single packet takes 4.5 seconds, you need to check your program and network latency
Mangsangtae is very good. → I think the translation is wrong
I’m going to write it here because the editing is blocked.
200kbyte binary file transmission and reception were successful through UDP communication.
The UDP server is sending 512 bytes individually, but it takes 30 minutes to receive them all…
The communication network is LGU+ and it is being tested in Korea, and the network is in good condition.
If there is anything good other than the UDP method, please recommend it.
From what you answered, it doesn’t seem like a problem
First, I’m using BC95-GV
It actually looks like it takes 4 to 6 seconds to get 512 bytes.
Is there a way to recommend it universally other than UDP?
BC95GV belongs to NB, which belongs to narrowband. The delay and network speed and delay you tested are normal
I don’t think there will be anything faster than UDP, but is there another protocol for receiving binary files faster than UDP?
No, I also think UDP is the best
